Example Calculation
Scenario: User wants a moderate trip with Golden Teacher mushrooms (dried).
- 1. Experience Level: Moderate Trip (12-18 mg)
- 2. Strain Family: P. Cubensis
- 3. Specific Strain: Golden Teacher (0.63%)
- 4. Mushroom Form: Dried
Result: 1.9g - 2.9g of dried Golden Teacher mushrooms needed.
Why? Golden Teacher contains approximately 0.63% psilocybin. To consume 12-18mg of the active compound, you need roughly 2 to 3 grams of dried mushroom material.
The Math behind the Magic:
To find the weight in grams, we divide the target dose (mg) by the concentration of psilocybin in the mushroom.
Formula:
Weight (g) = Target Dose (mg) / (Percentage × 10)
Step 1 (Convert % to mg/g):
0.63% means there are 6.3mg of psilocybin in every 1 gram of dried mushroom.
Step 2 (Calculate Range):
Min: 12mg / 6.3 = 1.90g
Max: 18mg / 6.3 = 2.85g
Result: You need between 1.9g and 2.9g.
⚠️ Important Disclaimer
Please note that the results provided by this calculator are based on average potency values. In nature, psilocybin content can vary significantly due to genetics and growing conditions. Active compound levels can differ even within the same flush or within the exact same mushroom.

Frequently Asked Questions
Our calculator provides an accurate estimate based on the average active compound levels for each strain. However, it is crucial to remember that these percentages are averages. The actual potency can vary between individual mushrooms and even different flushes of the same strain.
There has never been a recorded fatal overdose from psilocybin mushrooms directly. However, 'overdosing' in the sense of taking far too much is possible. Taking a dose that is too high can lead to an overwhelming, frightening, and psychologically challenging experience often called a 'bad trip'.
If you are a beginner, we strongly recommend starting with a low to medium dose within the 'Light Trip' range (approx. 1g - 1.5g of dried Cubensis). This allows you to safely understand how you feel and react. You can always take a larger dose on a future occasion.
Typically, you'll start to feel the first effects within 30 to 60 minutes. This onset time can vary depending on different factors, such as whether you consume them on a full or empty stomach (a full stomach can delay absorption). The overall experience usually lasts between 4 to 6 hours.
Fresh magic mushrooms consist of approximately 90% water. The drying process removes this water, which concentrates the active compounds by weight. This is why the required dose for dried mushrooms is significantly lower (roughly 10 times less) than for fresh mushrooms.
Scientific studies suggest that body weight, age, and gender do not have a significant or reliable impact on the intensity of a psilocybin experience. The primary factors are the specific dose and individual sensitivity.
